Highlight: David Bruton is at it again. The special-teams standout got a long look as a starting strong safety during last year's organized team activities (OTAs) and training camp, only to play sparingly during the regular season. After running with the third-string unit through the offseason and camp this year, Bruton received reps with the nickel unit Friday.

"Not taking it for granted by any means," he said.

One reason why Bruton may be getting the occasional serious rep now is by the second half of every season, he gets thrown in there at safety.

"I've always been blessed to that guy they can rely on whether somebody gets hurt, or somebody's not performing well, or somebody doesn't know the playbook as well — I'm always prepared," he said.

Lowlight: One difference between an NFL starting quarterback and backup is an ability to make instant decisions from the pocket. There are times when Brock Osweiler seems to hang on to the ball a tad long, although offensive coordinator Adam Gase says that's on him. Gase says he asks Osweiler to look to throw downfield first.

No. 3 quarterback Zac Dysert was picked off in the red zone by linebacker Jamar Cheney, who made a terrific leaping stab of the ball.

Position battle: When training camp began, a big question was whether Nate Irving could keep the job as the Broncos' starting middle linebacker. The question hasn't been asked much since camp opened last week.

"Nate Irving has had a real nice camp," said Broncos defensive coordinator Jack Del Rio. "He's a guy returning right now that is getting the first crack at it. He's a big, physical guy. He moves a little better than people think. He's intelligent."

"If you looked at the first day of practice and you looked at today, you'd go, 'Wow, doesn't even look like the same guy,"' Del Rio said. "He's progressing and we just have to see how far we can bring him."
